<Embodiment 1>
FIG. 1 is a perspective view showing a tray open state of the optical disc apparatus according to the first embodiment of the present invention, FIG. 2 is a perspective view showing a tray closed state, and FIG. 3 shows a tray closed state. 4 is a top view, and FIG. 4 is a bottom view showing a state in which the tray is pulled out partway.

  The optical disk apparatus according to the first embodiment includes a box-shaped case assembly 10 that houses a tray 20 on which an optical disk is mounted. The chassis assembly 10 includes a bottom case 11 that forms a substantially box shape with a bottom surface and three wall surfaces, and a top case 12 that is attached to the top surface of the bottom case 11. The case assembly 10 includes a thick and substantially box-shaped main body portion 13 and a thin wing portion 14 projecting from the main body portion 13 in the lateral direction (rightward as viewed from the opening).

  The tray 20 is accommodated in the main body 13 of the case assembly 10, and is extended in the lateral direction from the main body provided with the rotating shaft of the mounted optical disk, and is accommodated in the wing 14 of the case assembly 10. And a wing portion 25.

  As shown in FIG. 4, the wing portion 25 includes a rib 25 </ b> A extending in the moving direction of the tray 20 and a rib 25 </ b> B extending in the moving direction of the tray 20 on the lower surface side. The end portions on the lower surface side of the rib 25A constitute the same plane, and the wing portion 25 can have a predetermined strength by the ribs 25A and 25B.

  The tray 20 is supported by rails 31 and 32 on the left and right sides of the main body, and is slidably attached to the rails 31 and 32. Sliding portions on which the rails 31 and 32 slide are provided on the left and right side surfaces in the chassis assembly 10. The tray 20 is moved by the rails 31 and 32 and the sliding portion so as to protrude from the inside of the case assembly to the outside of the case assembly, and is in a tray open state (FIG. 1). Further, the tray 20 moves from the outside of the case assembly to a position where it is accommodated in the case assembly, and enters the tray closed state (FIG. 2).

  A bezel 40 is attached to the front surface of the tray 20 as indicated by broken arrows in FIGS. The bezel 40 coincides with the position of the front panel 50 (see FIG. 10) of the device to which the optical disk device is mounted, and is operated to open and close the tray 45 and the window 45 that guides light from the access lamp. And an opening / closing button 46, and a hole 47 for operating a manual ejection mechanism provided inside the optical disc apparatus.

  The bezel 40 is engaged with a protrusion 41 that engages with the left reference hole 21 on the front surface of the tray 20, a hook 42 that engages with the engagement hole 22, and an engagement portion 23 that is provided at a step on the side surface of the tray 20. And a hook 44 that engages with an engagement hole 24 provided on the left side of the front surface of the tray 20. The bezel 40 is attached to the tray 20 by the engagement between these engaging portions and hooks. In particular, the attachment position of the bezel 40 to the tray 20 is determined by the left reference hole 21 and the right engagement hole 24 on the front surface of the tray 20.

  Since the tray 20 is usually formed by resin molding, warping occurs during molding. Further, when a force is applied to the tray 20 during the assembling operation, the variation in the shape of the tray 20 such as warping becomes large. In particular, since the wing portion 25 of the tray 20 is thin and protrudes laterally from the main body, it is structurally weak and easily deformed.

  On the upper surface of the top case 12, a spring-shaped convex portion 15 that protrudes inside the case assembly 10 is provided. As shown in FIGS. 4 and 5, a convex portion 16 that protrudes to the inside of the case assembly 10 is provided at substantially the same position as the spring 15 on the lower surface of the bottom case 11.

  Since the ribs 25A and 25B are provided on the lower surface side of the tray 20, the portions other than the portions where the ribs are provided are uneven. For this reason, the convex part 16 is provided in the position facing the rib 25A so that the convex part 16 always contacts the tray 20 in the process in which the tray 20 is accommodated in the case assembly 10. In addition, you may provide the convex part 16 in the position which opposes the outer rib 25C instead of the position which opposes the internal rib 25A.

  Inside the chassis assembly 10 is housed a printed circuit board on which an interface connector and an interface circuit for connecting the optical disk device to a computer are mounted. Further, a printed circuit board on which a drive circuit for driving an optical pickup for reading a signal from an optical disk mounted on the optical disk apparatus is mounted on the tray 20. The printed circuit board accommodated in the chassis assembly 10 and the printed circuit board attached to the tray 20 are connected by a flexible connection member (for example, a flexible flat cable, a flexible circuit board, etc.).

  FIG. 5 is a BB sectional view of the optical disc apparatus according to the first embodiment of the present invention.

  The tip of the spring 15 faces outside (upper surface side), and comes into contact with the upper surface of the wing portion 25 of the tray 20 in the middle. The spring 15 is formed by, for example, cutting a part of the top case 12 inward by pressing. The part of the spring 15 that contacts the tray 20 forms a curved surface. Further, the spring 15 is cut and raised from the opening side of the chassis assembly 10, and the inclination on the opening side is gentle. For this reason, when the tray 20 is stored in the case assembly 10, the tray 20 can be prevented from being caught by the spring 15, and the drag force during storage can be reduced.

  The convex portion 16 is provided at substantially the same (opposite) position as the spring 15 on the lower surface of the bottom case 11, and a protrusion having a rounded tip is formed by drawing a part of the bottom case. . The tip of the convex portion 16 contacts the lower surface of the wing portion 25 of the tray 20.

  By configuring the spring 15 and the convex portion 16 in this way, the spring 15 and the convex portion 16 can sandwich the wing portion 25 when the tray 20 is stored in the case assembly 10. For this reason, since the tray 20 is regulated at the correct position in the tray closed state, the inclination of the bezel 40 attached to the front surface of the tray 20 can be suppressed.

  In the first embodiment, the top case 12 is provided with the spring 15, and the bottom case 11 is provided with the convex portion 16. However, either the top case 12 or the bottom case 11 is provided with the spring, and any one is provided with the convex portion. May be. For example, in addition to the illustrated combinations, a convex portion may be provided on the top case 12 and a spring may be provided on the bottom case 11. Furthermore, springs may be provided on both the top case 12 and the bottom case 11, and convex portions may be provided on both the top case 12 and the bottom case 11. In addition, by providing a spring on at least one side, the resistance force when the tray 20 is housed in the chassis assembly 10 can be reduced, and the tray 20 can be smoothly inserted and removed. Further, by providing a convex portion on at least one of the trays 20, variations in the position of the tray 20 in the chassis assembly 10 can be reduced. Therefore, when a spring is provided on one side and a convex part is provided on the other side, the restriction of the position of the tray 20 in the chassis assembly 10 and the reduction of the resistance force when the tray 20 is stored in the chassis assembly 10 are compatible. be able to .

  Further, only one of the spring 15 or the convex portion 16 may be provided. For example, when the right end portion of the tray 20 is warped upward, the spring 15 (or the convex portion) presses the tray 20 downward, so that the tray 20 can be brought into a correct position. On the other hand, when the right end portion of the tray 20 warps downward, the convex portion 16 (or a spring) presses the tray 20 upward, so that the tray 20 can be in the correct position. Thereby, the inclination of the bezel 40 can be suppressed.

  In addition, when providing a spring or a convex part in one of the top case 12 or the bottom case 11, it is good to provide in the top case 11. This is because the wing portion 25 often warps upward due to the shape of the tray 20.

  As described above, according to the first embodiment of the present invention, the tray 20 is stored by providing at least one of the springs or the convex portions (15, 16) projecting inward from the case assembly 10. The position in the chassis assembly 10 at the time can be restricted, and the inclination of the bezel 40 attached to the tray 20 can be suppressed.
